I think its the same as the BX-Its a bit easier than most bearing jobs because the bearing comes as part of a new hub-disc carrier. Thats why it costs more than a plain bearing.
You will need a hub puller, if you haven't got one or seen one, this is the sort of thing you need-

Remove the brake caliper-you shouldn't need to disconnect the hydraulics, as it only needs to go far enough to get the disc off.
Take the brake disc off, and undo the big bolt in the middle of the hub which holds it all on-sorry,I can't remember the size of this. Then pull off the hub and the bearing outer race comes with it- you then have to spend a bit of time hacking the inner race off the stub-axle. I cut into it with a grinder and then split it with a cold-chisel.
Then, hopefully, you should have a bare stub axle and you push the new hub assembly on, refit the disc and caliper, put a new bolt on, which should come with the bearing, put the wheel on, and job done!!!
It sounds worse than it is-take the back wheel off and have a look and it all becomes clear- the main problem I found doing it on the BX was getting the bearing water shield on without damaging it.
